Activated factor Xa, whose major practical role is the
generation of thrombin by the limited proteolysis of
prothrombin, holds a central position that links the
intrinsic and extrinsic activation mechanisms in the final
common pathway of blood coagulation. The generation of.',
thrombin, the final serine protease in the pathway to
generate a fibrin clot, from its precursor is amplified by
formation of prothrombinase complex (factor Xa, factor
Ca^+ and phospholipid). Since it is calculated that one
molecule of factor Xa can generate 138 molecules of
thrombin (Elodi, S., Varadi, K.: Optimization of conditions
for the catalytic effect of the factor IXa-factor VIII
Complex: Probable role of the complex in the amplification
of blood coagulation. Thromb. Res. 1979, 15, 617-629),
inhibition of factor Xa may be more efficient than
inactivation of thrombin in interrupting the blood
coagulation system.
Therefore, efficacious and specific inhibitors of
factor Xa are needed as potentially valuable therapeutic
agents for the treatment of thromboembolic disorders. It
is thus desirable to discover new factor Xa inhibitors. In
addition, it is also desirable to find new compounds with
improved pharmacological characteristics compared with
known factor Xa inhibitors. For example, it is preferred
to find new compounds with improved factor Xa inhibitory
activity and selectivity for factor Xa versus other serine
proteases (i.e., trypsin). It is also desirable and
preferable to find compounds with advantageous and improved
characteristics in one or more of the following categories,
but are not limited to: (a) pharmaceutical properties
(e.g., solubility, permeability, and amenability to
sustained release formulations); (b) dosage requirements
(e.g., lower dosages and/or once-daily dosing); (c) factors
which decrease blood concentration peak-to-trough
characteristics (e.g., clearance and/or volume of
distribution); (d) factors that increase the concentration
of active drug at the receptor (e.g., protein binding,
volume of distribution); (e) factors that decrease the
liability for clinical drug-drug interactions (e.g.,
cytochrome P450 enzyme inhibition or induction); (f)
factors that decrease the potential,for adverse sideeffects
(e.g., pharmacological selectivity beyond serine
proteases, potential chemical or metabolic reactivity, and
limited CNS penetration); and, (g) factors that improve
manufacturing costs or feasibility (e.g., difficulty of
synthesis, number of chiral centers, chemical stability,
and ease of handling).

specific forms without departing from the spirit or
essential attributes thereof. This invention encompasses
all combinations of preferred aspects of the invention
noted herein. It is understood that any and all
embodiments of the present invention may be taken in
conjunction with any other embodiment or embodiments to
describe additional more preferred embodiments. It is also
to be understood that each individual element of the
preferred embodiments is intended to be taken individually
as its own independent preferred embodiment. Furthermore,
any element of an embodiment is meant to be combined with
any and all other elements from any embodiment to describe
an additional embodiment.
DEFINITIONS
The compounds herein described may have asymmetric
centers. Compounds of the present invention containing an
asymmetrically substituted atom may be isolated in
optically active or racemic forms. It is well known in the
art how to prepare optically active forms, such as by
resolution of racemic forms or by synthesis from optically
active starting materials,. Many geometric isomers of
olefins, C=N double bonds, and the like can also be present
in the compounds described herein, and all such stable
isomers are contemplated in the present invention. Cis and
trans geometric isomers of the compounds of the present
invention are described and may be isolated as a mixture of
isomers or as separated isomeric forms. All chiral,
diastereomeric, racemic forms and all geometric isomeric
forms of a structure are intended, unless the specific
stereochemistry or isomeric form is specifically indicated.
All processes used to prepare compounds of the present
invention and intermediates made therein are considered to
be part of the present invention. All tautomers of shown
or described compounds are also considered to be part of
the present invention.
Preferably, the molecular weight of compounds of the
present invention is less than about 500, 550, 600, 650,
700, 750, or 800 grams per mole. Preferably, the molecular
weight is less than about 800 grams per mole. More
preferably, the molecular weight is less than about 750
grams per mole. Even more preferably, the molecular weight
is less than about 700 grams per mole.
The term "substituted," as used herein, means that any
one or more hydrogens on the designated atom is replaced
with a selection from the indicated group, provided that
the designated atom's normal valency is not exceeded, and
that the substitution results in a stable compound. When a
substituent is keto (i.e., =0), then 2 hydrogens on the
atom are replaced. Keto substituents are not present on
aromatic moieties. Ring double bonds, as used herein, are
double bonds that are formed between two adjacent ring
atoms (e.g., C=C, C=N, or N=N). The present invention, in
general, does not cover groups such as N-halo, S(0)H, and
S02H.
The present invention is intended to include all
isotopes of atoms occurring in the present compounds.
Isotopes include those atoms having the same atomic.number
but different mass numbers. By way of general example and
without limitation, isotopes of hydrogen include tritium
and deuterium. Isotopes of carbon include C-13 and C-14.
When any variable (e.g., R6) occurs more than one time
in any constituent or formula for a compound, its
definition at each occurrence is independent of its
definition at every other occurrence. Thus, for example,
if a group is shown to be substituted with 0-2 R6, then
said group may optionally be substituted with up to two R6
groups and R6 at each occurrence is selected independently
from the definition of R6. Also, combinations of
substituents and/or variables are permissible only if such
combinations result in stable compounds.
When a bond to a substituent is shown to cross a bond
connecting two atoms in a ring, then such substituent may
be bonded to any atom on the ring. When a substituent is
listed without indicating the atom via which such
substituent is bonded to the rest of the compound of a
given formula, then such substituent may be bonded via any
atom in such substituent. Combinations of substituents
and/or variables are permissible only if such combinations
result in stable compounds.
In cases wherein there are amines on the compounds of
this invention, these can be converted to amine N-oxides by
treatment with an oxidizing agent (e.g., MCPBA and/or '
hydrogen peroxides) to afford other compounds of this
invention. Thus, all shown and claimed amines are
considered to cover both the shown amine and its N-oxide
(N—0) derivative.

ring. The nitrogen and sulfur heteroatoms may optionally
be oxidized (i.e., N-+0 and S(0)p) . The nitrogen atom may be
substituted or unsubstituted (i.e., N or NR wherein R is H
or another substituent, if defined). The heterocyclic ring
may be attached to its pendant group at any heteroatom or
carbon atom that results in a stable structure. The
heterocyclic rings described herein may be substituted on
carbon or on a nitrogen atom if the resulting compound is
stable. A nitrogen in the heterocycle may optionally be
guaternized. It is preferred that when the total number of
S and 0 atoms in the heterocycle exceeds 1, then these

scope of sound medical judgment, suitable for use in
contact with the tissues of human beings and animals
without excessive toxicity, irritation, allergic response,
or other problem or complication, commensurate with a
reasonable benefit/risk ratio.
As used herein, "pharmaceutically acceptable salts"
refer to derivatives of the disclosed compounds wherein the
parent compound is modified by making acid or base salts
thereof. Examples of pharmaceutical'ly acceptable salts
include, but are not limited to, mineral or organic acid
salts of basic residues such as amines; alkali or organic
salts of acidic residues such as carboxylic acids; and the
like. The pharmaceutically acceptable salts include the
conventional non-toxic salts or the quaternary ammonium
salts of the parent compound formed, for example, from nontoxic
inorganic or organic acids. For example, such
conventional non-toxic salts include those derived from
inorganic acids such as hydrochloric, hydrobromic,
sulfuric, sulfamic, phosphoric, nitric and the like; and
the salts prepared from organic acids such as acetic,
propionic, succinic, glycolic, stearic, lactic, malic,
tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic,
phenylacetic, glutamic, benzoic, salicyclic, sulfanilic, 2-
acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic,
ethane disulfonic, oxalic, isethionic, and the like.
The pharmaceutically acceptable salts of the present
invention can be synthesized from the parent compound that
contains a basic or acidic moiety by conventional chemical
methods. Generally, such salts can be prepared by reacting
the free acid or base forms of these compounds with a
stoichiometric amount of the appropriate base or acid in
water or in an organic solvent, or in a mixture of the two;
generally, non-aqueous media like ether, ethyl acetate,
ethanol, isopropanol, or acetonitrile are preferred. Lists
of suitable salts are found in Remington's Pharmaceutical
Sciences, 17th ed. , Mack Publishing Company, Easton, PA,
1985, p. 1418, the disclosure of which is hereby
incorporated by reference.
Since prodrugs are known to enhance numerous desirable
qualities of Pharmaceuticals (e.g., solubility,
bioavailability, manufacturing, etc.) the compounds of the
present invention may be delivered in prodrug form. Thus,
the present invention is intended to cover prodrugs of the
presently claimed compounds, methods of delivering the same
and compositions containing the same. "Prodrugs" are
intended to include any covalently bonded carriers that
release an active parent drug of the present invention in
vivo when such prodrug is administered to a mammalian
subject. Prodrugs the present invention are prepared by
modifying functional groups present in the compound in such
a way that the modifications are cleaved, either in routine
manipulation or in vivo, to the parent compound. Prodrugs
include compounds of the present invention wherein a
hydroxy, amino, or sulfhydryl group is bonded to any group
that, when the prodrug of the present invention is
administered to a mammalian subject, it cleaves to form a
free hydroxyl, free amino, or free sulfhydryl group,
respectively. Examples of prodrugs include, but are not
limited to, acetate, formate, and benzoate derivatives of
alcohol and amine functional groups in the compounds of the
present invention.
"Stable compound" and "stable structure" are meant to
indicate a compound that is sufficiently robust to survive
isolation to a useful degree of purity from a reaction
mixture, and formulation into an efficacious therapeutic
agent. It is preferred that there presently recited
compounds do not contain a N-halo, S(0)2H, or S(0)H group.
"Substituted" is intended to indicate that one or more
hydrogens on the atom indicated in the expression using
"substituted" is replaced with a selection from the
indicated group(s), provided that the indicated atom's
normal valency is not exceeded, and that the substitution
results in a stable compound. When a substituent is keto
(i.e., =O) group, then 2 hydrogens on the atom are
replaced.
As used herein, "treating" or "treatment" cover the
treatment of a disease-state in a mammal, particularly in a
human, and include: (a) preventing the disease-state from
occurring in a mammal, in particular, when such mammal is
predisposed to the disease-state but has not yet been
diagnosed as having it; (b) inhibiting the disease-state,
i.e., arresting it development; and/or (c) relieving the
disease-state, i.e., causing regression of the disease
state.
"Therapeutically effective amount" is intended to
include an amount of a compound of the present invention
that is effective when administered alone or in combination
to inhibit factor Xa. "Therapeutically effective amount"
142
is also intended to include an amount of the combination of
compounds claimed that is effective to inhibit factor Xa.
The combination of compounds is preferably a synergistic
combination. Synergy, as described, for example, by Chou
and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when
the effect (in this case, inhibition of factor Xa) of the
compounds when administered in combination is greater than
the additive effect of the compounds when administered
alone as a single agent. In general, a synergistic effect
is most clearly demonstrated at sub-optimal concentrations
of the compounds. Synergy can be in terms of lower
cytotoxicity, increased antithrombotic effect, or some
other beneficial effect of the combination compared with
the individual components.

Compounds of the present invention wherein ring P is
absent and ring M is a six-membered ring can be obtained as
shown in scheme 28. These types of compounds can be
obtained from commercially available anthranilic acids or
their anthranilates. Anthranilic acids or their nitro
precursors can be coupled with a suitable B-A-V (wherein V
is a amino functionality) in presence of a base such as
triethyl amine, pyridine, or DMAP. Subsequent coupling
with an appropriate acid chloride or aniline or
aminopyridyl should afford compounds of the present
invention.
2. Couple to G-C(0)C1, DMAP
In an analogous fashion the anthranilates can be
coupled with a suitable amine, aniline, or aminopyrimidyl
to afford the corresponding benzamide. The benzamides can
then be coupled with an appropriate B-A-V (wherein V is a
acid chloride derivative, an alkyl halide, or a sulfonyl
chloride) to afford additional compounds of the present
invention (see scheme 29).
Commercially available ring M derivatives bearing a
nitro and amino functionality can also be derivatized as
shown above to afford bisamide analogs. In this case,
coupling of the aniline with B-A-V (wherein V is an acid
chloride, a sulfonyl chloride, or an alkylhalide) affords
166
an intermediate that can be subjected to treatment with an
appropriate G-U (wherein U is either a acid chloride or an
alkyl halide) in presence of a suitable base such as DMAP.
It should be noted that the order of addition of B-A-V and
G-U can be reversed to obtain other compounds of the
present invention (see scheme 30).
It should be noted that the syntheses shown above
could be modified to use coupling intermediates such as
lodo-A-V, wherein V is an acid chloride, amino,
alkylhalide, or sulfonyl chloride. These in turn could be
coupled to a G-U group. The iodo intermediate could then
be subjected to Ullman or Buchwald coupling as described
previously to afford compounds of the present invention.
The iodo intermediate could also be converted to an amine
via standard Buchwald conditions to afford the
corresponding anilino intermediate. This in turn could be
coupled as previously described to afford compounds of the
present invention.
When M is a non-aromatic ring, the compounds of this
invention with general structure of Formula I can be
synthesized by using similar methods as described
previously and by those skilled in the art. One
diastereomer of a compound of Formula I may display better
activity compared with the others. Thus, the following
stereochemistries are considered to be a part o"f the
present invention.
When required, separation of the racemic material can
be achieved by HPLC using a chiral column or by a
resolution using a resolving agent such as camphonic
chloride as in Wilen, S. H. Tables of Resolving Agents and
Optical Resolutions 1972, 308 pp or using enantiomerically
pure acids and bases. A chiral compound of Formula I may
also be directly synthesized using a chiral catalyst or a
chiral ligand, e.g., Jacobsen, E. Ace. Chem. Res. 2000, 33,
421-431 or using other enantio- and diastereo-selective
reactions and reagents known to one skilled in the art of
asymmetric synthesis.
UTILITY
The compounds of this invention are inhibitors of
factor Xa and are useful as anticoagulants for the
treatment or prevention of thromboembolic disorders in
mammals (i.e., factor Xa-associated disorders). In
general, a thromboembolic disorder is a circulatory disease
caused by blood clots (i.e., diseases involving fibrin
formation, platelet activation, and/or platelet
aggregation). The term "thromboembolic disorders" as used
herein includes arterial cardiovascular thromboembolic
disorders, venous cardiovascular thromboembolic disorders,
and thromboembolic disorders in the chambers of the heart.
The term "thromboembolic disorders" as used herein also
includes specific disorders selected from, but not limited
to, unstable angina or other acute coronary syndromes,
first or recurrent myocardial infarction, ischemic sudden
168
death, transient ischemic attack, stroke, atherosclerosis,
peripheral occlusive arterial disease, venous thrombosis,
deep vein thrombosis, thrombophlebitis, arterial embolism,
coronary arterial thrombosis, cerebral arterial thrombosis,
cerebral embolism, kidney embolism, pulmonary embolism, and
thrombosis resulting from (a) prosthetic valves or other
implants, (b) indwelling catheters, (c) stents, (d)
cardiopulmonary bypass, (e) hemodialysis, or (f) other
procedures in which blood is exposed to an artificial
surface that promotes thrombosis. It is noted that
thrombosis includes occlusion (e.g. after a bypass) and
reocclusion (e.g., during or after percutaneous
transluminal coronary angioplasty). The thromboembolic
disorders may result from conditions including but not
limited to atherosclerosis, surgery or surgical
complications, prolonged immobilization, arterial
fibrillation, congenital thrombophilia, cancer, diabetes,
effects of medications or hormones, and complications of
pregnancy. The anticoagulant effect of compounds of the
present invention is believed to be due to inhibition of
factor Xa or thrombin.
The effectiveness of compounds of the present
invention as inhibitors of factor Xa was determined using
purified human factor Xa and synthetic substrate. The rate
of factor Xa hydrolysis of chromogenic substrate S2222
(Diapharma/Chromogenix, West Chester, OH) was measured both
in the absence and presence of compounds of the present
invention. Hydrolysis of the substrate resulted in the
release of pNA, which was monitored spectrophotometrically
by measuring the increase in absorbance at 405 run. A
decrease in the rate of absorbance change at 405 nm in the
presence of inhibitor is indicative of enzyme inhibition.
The results of this assay are expressed as inhibitory
constant, Kj..
Factor Xa determinations were made in 0.10 M sodium
phosphate buffer, pH 7.5, containing 0.20 M NaCl, and 0.5%
169
PEG 8000. The Michaelis constant, Km, for substrate
hydrolysis was determined at 25 °C using the method of
Lineweaver and Burk. Values of Ki were determined by
allowing 0.2-0.5 nM human factor Xa (Enzyme Research
Laboratories, South Bend, IN) to react with the substrate
(0.20 mM - 1 mM) in the presence of inhibitor. Reactions
were allowed to go for 30 min and the velocities (rate of
absorbance change vs. time) were measured in the time frame
of 25-30 min. The following relationship was used to
calculate Ki values:
(v0-vs)/vs = I/(Ki (1+ S/Km))
where:
v0 is the velocity of the control in the absence of
inhibitor;
vs is the velocity in the presence of inhibitor;
I is the concentration of inhibitor;
Ki is the dissociation constant of the
enzyme:inhibitor complex;
S is the concentration of substrate;
Km is the Michaelis constant.
Compounds tested in the above assay are considered to
be active if they exhibit a KI of compounds of the present invention have KI'S of More preferred compounds of the present invention have Kj/s0.1 uM. Even more preferred compounds of the present
invention have Kj/s of compounds of the present invention have KI'S of Using the methodology described above, a number of
compounds of the present invention were found to exhibit
KI'S of compounds of the present invention as effective Xa
inhibitors.
The antithrombotic effect of compounds of the present
invention can be demonstrated in a rabbit arterio-venous
(AV) shunt thrombosis model. In this model, rabbits
weighing 2-3 kg anesthetized with a mixture of xylazine (10
rag/kg i.m.) and ketamine (50 mg/kg i.m.) are used. A
saline-filled AV shunt device is connected between the
femoral arterial and the femoral venous cannulae. The AV
shunt device consists of a piece of 6-cm tygon tubing that
contains a piece of silk thread. Blood will flow from the
femoral artery via the AV-shunt into the femoral vein. The
exposure of flowing blood to a silk thread will induce the
formation of a significant thrombus. After 40 min, the
shunt is disconnected and the silk thread covered with
thrombus is weighed. Test agents or vehicle will be given
(i.v., i.p., s.c., or orally) prior to the opening of the
AV shunt. The percentage inhibition of thrombus formation
is determined for each treatment group. The ID5Q values
(dose which produces 50% inhibition of thrombus formation)
are estimated by linear regression.
The compounds of the present invention may also be
useful as inhibitors of serine proteases, notably human
thrombin, Factor Vila, Factor IXa, Factor XIa, urokinase,
plasma kallikrein, and plasmin. Because of their
inhibitory action, these compounds are indicated for use in
the prevention or treatment of physiological reactions,
blood coagulation and inflammation, catalyzed by the
aforesaid class of enzymes. Specifically, the compounds
have utility as drugs for the treatment of diseases arising
from elevated thrombin activity such as myocardial
infarction, and as reagents used as anticoagulants in the
processing of blood to plasma for diagnostic and other
commercial purposes.
Some compounds of the present invention were shown to
be direct acting inhibitors of the serine protease thrombin
by their ability to inhibit the cleavage of small molecule
substrates by thrombin in a purified system. In vitro
inhibition constants were determined by the method
described by Kettner et al. in J. Biol. Chem. 265, 18289-
18297 (1990), herein incorporated by reference. In these
assays, thrombin-mediated hydrolysis of the chromogenic
substrate S2238 (Helena Laboratories, Beaumont, TX) was
monitored spectrophotometrically. Addition of an inhibitor
to the assay mixture results in decreased absorbance and is
indicative of thrombin inhibition. Human thrombin (Enzyme
Research Laboratories, Inc., South Bend, IN) at a
concentration of 0.2 nM in 0.10 M sodium phosphate buffer,
pH 7.5, 0.20 M NaCl, and 0.5% PEG 6000, was incubated with
various substrate concentrations ranging from 0.20 to 0.02
mM. After 25 to 30 min of incubation, thrombin activity
was assayed by monitoring the rate of increase in
absorbance at 405 nm that arises owing to substrate
hydrolysis. Inhibition constants were derived from
reciprocal plots of the reaction velocity as a function of
substrate concentration using the standard method of
Lineweaver and Burk. Using the methodology described
above, some compounds of this invention were evaluated and
found to exhibit a Ki of less than 10 uM, thereby
confirming the utility of the compounds of the present
invention as effective thrombin inhibitors.
The compounds are administered to a mammal in a
therapeutically effective amount. By "therapeutically
effective amount" it is meant an amount of a compound of
the present invention that, when administered alone or in
combination with an additional therapeutic agent to a
mammal, is effective to treat a thromboembolic condition or
disease.

Administration of the compounds of the present
invention (i.e., a first therapeutic agent) in combination
with at least one additional therapeutic agent (i.e., a
second therapeutic agent), preferably affords an efficacy
advantage over the compounds and agents alone, preferably
while permitting the use of lower doses of each (i.e., a
synergistic combination). A lower dosage minimizes the
potential of side effects, thereby providing an increased
margin of safety. It is preferred that at least one of the
therapeutic agents is administered in a sub-therapeutic
dose. It is even more preferred that all of the
therapeutic agents be administered in sub-therapeutic
doses. Sub-therapeutic is intended to mean an amount of a
therapeutic agent that by itself does not give the desired
therapeutic effect for the condition or disease being
treated. Synergistic combination is intended to mean that
the observed effect of the combination is greater than the
sum of the individual agents administered alone.
The compounds of the present invention are also useful
as standard-or reference compounds, for example as a
quality standard or control, in tests or assays involving
the inhibition of factor Xa. Such compounds may be
provided in a commercial kit, for example, for use in
pharmaceutical research involving factor Xa. For example,
a compound of the present invention could be used as a
reference in an assay to compare its known activity to a
compound with an unknown activity. This would ensure the
experimenter that the assay was being performed properly
and provide a basis for comparison, especially if the test
compound was a derivative of the reference compound. When
developing new assays or protocols, compounds according to
the present invention could be used to test their
effectiveness.
The compounds of the present invention may also be
used in diagnostic assays involving factor Xa. For
example, the presence of factor Xa in an unknown sample
could be determined by addition of chromogenic substrate
S2222 to a series of solutions containing test sample and
optionally one of the compounds of the present invention.
If production of pNA is observed in the solutions
containing test sample, but not in the presence of a
compound of the present invention, then one would conclude
factor Xa was present.
Compounds of the present invention may further be
useful as diagnostic agents and adjuncts. For example, the
present compounds may be useful in maintaining whole and
fractionated blood in the fluid phase such as required for
analytical and biological testing.
The present invention also encompasses an article of
manufacture. As used herein, article of manufacture is
intended to include, but not be limited to, kits and
packages. The article of manufacture of the present
invention, comprises: (a) a first container; (b) a
pharmaceutical composition located within the first
container, wherein the composition, comprises: a first
therapeutic agent, comprising: a compound of the present
invention or a pharmaceutically acceptable salt form
thereof; and, (c) a package insert stating that the
pharmaceutical composition can be used for the treatment of
a thromboembolic disorder (as defined previously) . In
another embodiment, the package insert states that the
pharmaceutical composition can be used in combination (as
defined previously) with a second therapeutic agent to
treat a thromboembolic disorder. The article of
manufacture can further comprise: (d) a second container,
wherein components (a) and (b) are located within the
second container and component (c) is located within or
outside of the second container. Located within the first
and second containers means that the respective container
holds the item within its boundaries.
The first container is a receptacle used to hold a
pharmaceutical composition. This container can be for
manufacturing, storing, shipping, and/or individual/bulk
selling. First container is intended to cover a bottle,
jar, vial, flask, syringe, tube (e.g., for a cream
preparation), or any other container used to manufacture,
hold, store, or distribute a pharmaceutical product.
The second container is one used to hold the first
container and, optionally, the package insert. Examples of
the second container include, but are not limited to, boxes
(e.g., cardboard or plastic), crates, cartons, bags (e.g.,
paper or plastic bags), pouches, and sacks. The package
insert can be physically attached to the outside of the
first container via tape, glue, staple, or another method
of attachment, or it can rest inside the second container
without any physical means of attachment to the first
container. Alternatively, the package insert is located on
the outside of the second container. When located on the
outside of the second container, it is preferable that the
package insert is physically attached via tape, glue,
staple, or another method of attachment. Alternatively, it
can be adjacent to or touching the outside of the second
container without being physically attached.
The package insert is a label, tag, marker, etc. that
recites information relating to the pharmaceutical
composition located within the first container. The
information recited will usually be determined by the
regulatory agency governing the area in which the article
of manufacture is to be sold (e.g., the United States Food
and Drug Administration). Preferably, the package insert
specifically recites the indications for which the
pharmaceutical composition has been approved. The package
insert may be made of any material on which a person can
read information contained therein or thereon. Preferably,
the package insert.is a printable material (e.g., paper,
plastic, cardboard, foil, adhesive-backed paper or plastic,
etc.) on which the desired information has been formed
(e.g., printed or applied).
Dosage and Formulation
The compounds of this invention can be administered in
such oral dosage forms as tablets, capsules (each of which
includes sustained release or timed release formulations),
pills, powders, granules, elixirs, tinctures, suspensions,
syrups, and emulsions. They may also be administered in
intravenous (bolus or infusion), intraperitoneal,
subcutaneous, or intramuscular form, all using dosage forms
well known to those of ordinary skill.in the pharmaceutical
arts. They can'be administered alone, but generally will
be administered with a pharmaceutical carrier selected on
the basis of the chosen route of administration and
standard pharmaceutical practice.
The dosage regimen for the compounds of the present
invention will, of course, vary depending upon known
factors, such as the pharmacodynamic characteristics of the
particular agent and its mode and route of administration;
the species, age, sex, health, medical condition, and
weight of the recipient; the nature and extent of the
symptoms; the kind of concurrent treatment; the frequency
of treatment; the route of administration, the renal and
hepatic function of the patient, and the effect desired. A
physician- or veterinarian can determine and prescribe the
effective amount of the drug required to prevent, counter,
or arrest the progress of the thromboembolic disorder.
By way of general guidance, the daily oral dosage of
each active ingredient, when used for the indicated
effects, will range between about 0.001 to 1000 mg/kg of
body weight, preferably between about 0.01 to 100 mg/kg of
body .weight per day, and most preferably between about 1,. 0
to 20 mg/kg/day. Intravenously, the most preferred doses
will range from about 1 to about 10 mg/kg/min during a
constant rate infusion. Compounds of this invention may be
administered in a single daily dose, or the total daily
dosage may be administered in divided doses of two, three,
or four times daily.
Compounds of this invention can be administered in
intranasal form via topical use of suitable intranasal
vehicles, or via transdermal routes, using transdermal skin
patches. When administered in the form of a transdermal
delivery system, the dosage administration will, of course,
be continuous rather than intermittent throughout the
dosage regimen.
The compounds are typically administered in admixture
with suitable pharmaceutical diluents, excipients, or
carriers (collectively referred to herein as pharmaceutical
carriers) suitably selected with respect to the intended
form of administration, that is, oral tablets, capsules,
elixirs, syrups and the like, and consistent with
conventional pharmaceutical practices.
For instance, for oral administration in the form of- a
tablet or capsule, the active drug component can be
combined with an oral, non-toxic, pharmaceutically
acceptable, inert carrier such as lactose, starch, sucrose,
glucose, methyl cellulose, magnesium stearate, dicalcium
phosphate, calcium sulfate, mannitol, sorbitol and the
like; for oral administration in liquid form, the oral drug
components can be combined with any oral, non-toxic,
pharmaceutically acceptable inert carrier such as ethanol,
glycerol, water, and the like. Moreover, when desired or
necessary, suitable binders, lubricants, disintegrating
agents, and coloring agents can also be incorporated into
the mixture. Suitable binders include starch, gelatin,
natural sugars such as glucose or beta-lactose, corn
sweeteners, natural and synthetic gums such as acacia,,
tragacanth, or sodium alginate, carboxymethylcellulose,
polyethylene glycol, waxes, and the like. Lubricants used
in these dosage forms include sodium'oleate, sodium
stearate, magnesium stearate, sodium behzoate, sodium
acetate, sodium chloride, and the like. Disintegrators
include, without limitation, starch, methyl cellulose,
agar, bentonite, xanthan gum, and the like.
The compounds of the present invention can also be
administered in the form of liposome delivery systems, such
as small unilamellar vesicles, large unilamellar vesicles,
and multilamellar vesicles. Liposomes can be formed from a
variety of phospholipids, such as cholesterol,
stearylamine, or phosphatidylcholines.
Compounds of the present invention may also be coupled
with soluble polymers as targetable drug carriers. Such
polymers can include polyvinylpyrrolidone, pyran copolymer,
po lyhydr oxypr opy Ime thacry 1 ami de-pheno 1,
polyhydroxyethylaspartamidephenol, or polyethyleneoxidepolylysine
substituted with palmitoyl residues.
Furthermore, the compounds of the present invention may be
coupled to a class of biodegradable polymers useful in
achieving controlled release -of a drug, for example,
polylactic acid, polyglycolic acid, copolymers of
polylactic and polyglycolic acid, polyepsilon caprolactone,
polyhydroxy butyric acid, polyorthoesters, polyacetals,
polydihydropyrans, polycyanoacylates, and crosslinked or
amphipathic block copolymers of hydrogels.
Dosage forms (pharmaceutical compositions) suitable
for administration may contain from about 1 mg to about
mg of active ingredient per dosage unit. In these
pharmaceutical compositions the active ingredient will
ordinarily be present in an amount of about 0.5-95% by
weight based on the total weight of the composition.
Gelatin capsules may contain the active ingredient and
powdered carriers, such as lactose, starch, cellulose
derivatives, magnesium stearate, stearic acid, and the
like. Similar diluents can be used to make compressed
tablets. Both tablets and capsules can be manufactured as
sustained release products to provide for continuous
release of medication over a period of hours. Compressed
tablets can be sugar coated or film coated to mask any
unpleasant taste and protect the tablet from the
atmosphere, or enteric coated for selective disintegration
in the gastrointestinal tract.
Liquid dosage forms for oral administration can
contain coloring and flavoring to increase patient
acceptance.
In general, water, a suitable oil, saline, aqueous
dextrose (glucose), and related sugar solutions and glycols
such as propylene glycol or polyethylene glycols are
suitable carriers for parenteral solutions. Solutions for'
parenteral administration preferably contain a water
soluble salt of the active ingredient, suitable stabilizing
agents, and if necessary, buffer substances. Antioxidizing
agents such as sodium bisulfite, sodium sulfite, or
ascorbic acid, either alone or combined, are suitable
stabilizing agents. Also used are citric acid and its
salts and sodium EDTA. In addition, parenteral solutions
can contain preservatives, such as benzalkonium chloride,
methyl-or propyl-paraben, and chlorobutanol.
Suitable pharmaceutical carriers are described in
Remington's Pharmaceutical Sciences, Mack Publishing
Company, a standard reference text in this field.
Representative useful pharmaceutical dosage-forms for
administration of the compounds of this -invention can be
illustrated as follows:
Capsules
A large number of unit capsules can be prepared by
filling standard two-piece hard gelatin capsules each with
.100 mg of powdered active ingredient, 150 mg of lactose, 50
mg of cellulose, and 6 mg magnesium stearate.
Soft Gelatin Capsules
A mixture of active ingredient in a digestible oil
such as soybean oil, cottonseed oil or olive oil may be
prepared and injected by means of a positive displacement
pump into gelatin to form soft gelatin capsules containing
185
100 mg of the active ingredient. ' The capsules should be
washed and dried
Tablets
Tablets may be prepared by conventional procedures so
that the dosage unit is 100 mg of active ingredient, 0.2 mg
of colloidal silicon dioxide, 5 mg of magnesium-stearate,.
275 mg of microcrystalline cellulose, 11 mg of starch and
98.8 mg of lactose. Appropriate coatings may be applied to
increase palatability or delay absorption.
. Injectable
A parenteral composition suitable for administration
by injection may be prepared by stirring '1.5% by weight of
active ingredient in 10% by volume prqpylene glycol and
water. The solution should be made isotonic with sodium
chloride and sterilized.
Suspension
An aqueous suspension can be prepared.for oral
administration so that each 5 mL' contain 1.00 mg of finely
divided active ingredient, 200 mg of sodium carboxymethyl
cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol
solution, U.S.P, and 0.025 mL of vanillin.
Where the compounds of this invention are combined
with other anticoagulant agents, for example, a daily
dosage may be about 0.1 to 100 mg.of the compound of
Formula I and about 1 to 7.5 mg of the second
anticoagulant, per kilogram of patient body weight. For a
tablet dosage form, the compounds of. this invention
generally may be present in an amount of about 5 to 10 mg
per dosage unit, and the second anti-coagulant in an amount
of about 1 to 5 mg per dosage unit.
Where the compounds of the present invention are
.administered in combination with an anti-platelet agent, by
way of general guidance, typically a daily dosage may :be
186
about 0.01 to 25 mg of the compound of Formula I and about
50 to 150 mg of the anti-platelet agent, preferably about
0.1 to 1 mg of the compound of Formula I and about 1 to 3
mg of antiplatelet agents, per kilogram of patient body
weight.
Where the compounds of Formula I are administered in
combination with thrombolytic agent, typically a daily
dosage may be about 0.1 to 1 mg of the compound of Formula
I, per. kilogram of patient body weight and, in the case of •
the thrombolytic agents, the usual dosage of the
thrombolyic agent when administered alone may be reduced by
about 70-80% when administered with a compound of Formula
I. .
Where two or more of the foregoing second therapeutic
agents are administered with the compound of Formula I,
generally the amount of each component in a typical daily
dosage and typical dosage form may -be reduced relative to
the usual dosage of the agent when administered alone, in
view of the additive or synergistic effect of the
therapeutic agents when administered in combination.
Particularly.when provided as a single dosage unit,
the potential exists for a chemical interaction between the
combined active ingredients. For this reason, when the
compound of Formula I and a second therapeutic agent are
combined in a single dosage unit they are formulated such
that although the active ingredients are combined in a
single dosage unit, the physical contact between the active
ingredients is minimized (that is, reduced). For example,
one active ingredient may be enteric coated. By enteric
coating one of the active ingredients, it is possible not
only to minimize the contact between the.combined active
ingredients, but also, it is possible to control the
release of one of these components in the gastrointestinal
tract such .that one of these components is not released in
the stomach but rather is released in the intestines. One
of the active ingredients may also be coated with a
187
material that affects a sustained-release throughout the
gastrointestinal tract and also serves to minimize physical
contact between the combined active ingredients.
Furthermore, the sustained-released component can be
additionally enteric coated such that the release of this
component occurs only in the intestine. Still another
approach would involve the formulation of a combination
product in which the one component is coated with a
sustained and/or enteric release polymer, and the other
component is also coated with a polymer such as a lowviscosity
grade of hydroxypropyl-methylcellulose (HPMC) or
other appropriate materials as known in the art, in order
to further separate the active components. The polymer
• coating serves to form an additional barrier to interaction
with the other component.
These as well as other ways of minimizing contact
between the components of combination products of the
present invention, whether administered in a single dosage
form or administered in separate forms but at the same time
by the same manner, will be readily apparent to those
skilled in the art,.once armed with the present disclosure.
Other features of the invention will become apparent
in the course of the following descriptions of exemplary
embodiments that are afforded for illustration of the
invention and are not intended to be limiting thereof.

1-yl)-phenyl]-1,4,5,6-tetrahydro-pyrazolo[3,4-
c]pyridin-7-one
Part A. 3-Chloroaniline (5.00 g, 39.2 mmol) was added
dropwise to an ice-cold IN hydrochloric acid solution
followed by the addition of 4 mL of 12M hydrochloric acid.
To this solution was slowly added an ice-cold solution of
sodium nitrite (3.00 g, 43.1 mmol) in 4 mL of water while
maintaining the internal temperature to less than 5 °C.
This solution was stirred for 45 min at 0 °C during which
time a precipitate formed. Glacial acetic acid (1 mL) was
added and the precipitate dissolved. To this solution was
added solid sodium acetate (approx. 2 g) to adjust the pH
to 4 and then 10 mL ice cold acetone was added followed by
an ice cold solution of 1-chloro-l-methanesulfohyl-propan-
2-one in 10 mL acetone. The reaction was allowed to warm
to ambient temperature and stirred for 14 h. A stream of
nitrogen was passed over the solution to slightly reduce
the solvent volume. The solid precipitate was collected by
filtration, washed twice with water, and dried in vacua at
40 °C to give 8.47 g (81%) of N-(3-chlorophenyl)-1-
(methylsulfonyl)-methanehydrazonoyl chloride as a light
orange solid.
The methanehydrazonoyl chloride (8.47 g, 31.7 itimol) and 1-
(4-iodo-phenyl)-3~morpholin-4-yl-5,6-dihydro-lH-pyridin-2-
.one (12.17 g, 31.7 itimol) .were combined in anhydrous
toluene. The solution heated to 70 °C and triethylamine
(13.2 mL, 95.1 mmol) was added dropwise. After the
addition was complete the reaction was warmed to 90 °C and
stirred at this temperature for 14 h. Analysis by LC/MS
indicated formation of 1-(3-chloro-phenyl)-6-(4-iodophenyl)
-3-methanesulfonyl-7a-morpholin-4-yl-l,3a,4,5,6,7ahexahydro-
pyrazolo[3,4-c]pyridin-7-one complete with less
than 5% of 1-(4-iodo-phenyl)-3-morpholin-4-yl-5,6-dihydrolH-
pyridin-2-one remaining. The solvent was removed in
vacua. To the viscous oil was added dichloromethane (50
mL) then trifluoroacetic acid (30 mL) and heated to reflux
for 4 h. The solvent was evaporated and the residue
purified by flash column chromatography eluting with a
gradient of hexane to 40% ethylacetate/hexane to give 10.65
g (64%) of 1-(3-chloro-phenyl)-6-(4-iodo-phenyl)-3-
methanesulfonyl-1,4,5,6-tetrahydro-pyrazolo[3,4-c]pyridin-
7-one.
Part B. In a round bottomed flask were combined l-(3-
chloro-phenyl)-6-(4-iodo-phenyl)-3-methanesulfonyl-1, 4,5,6-
tetrahydro-pyrazolo[3,4-c]pyridin-7-one (1.00 g, 1.89
mmol), 5-valerolactam (0.36 g, 3.79 mmol), anhydrous
powdered potassium carbonate (1.05 g, 7.58 mmol), cuprous
iodide (0.072 g, 0.38 mmol), and 1,10-phenanthroline (0.068
g, 0.38 mmol). The flask was purge with argon and degassed
methylsulfoxide (10 mL) was added before heating to 120 °C.
Upon completion of the reaction, as judged by TLC or LC/MS,
the reaction was cooled to ambient temperature and 50 mL
each of 3M ammonium hydroxide and dichloromethane were
added. The phases were separated and the aqueous extracted
with an additional 30 mL of dichloromethane. The combined
dichloromethane extracts are washed successively four times
with water and once with brine. The solution was dried
over sodium sulfate, filtered, and evaporated to give an
oil that was purified by flash column chromatography
eluting with ethylacetate to give 0.424 g (45%) of l-(3-
chloro-phenyl)-3-methanesulfonyl-6-[4-(2-oxo-piperidin-lyl)
